IMPROVEMENT IN GATE-LATCHES.

Specification forming part of Letters Patent No. 593,750, dated July 31,1877; application filed May 2, 1877.

To all whom it may concern:

Be it known that I, JOHN D. CAMERON, of Chippewa Falls, in the county ofChippewa and State of Wisconsin, have invented certain new and usefulImprovements in Gate- Latches; and Ido hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanyin g drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to the class of gatelatches which are operated by avertical rod, generally placed so that a knob on the end of the rodcomes at the top of the gate, and when this knob is pushed down thegate-fastening is released.

My invention, which consists of the arrangement and combination of partsherein described, will be fully understood from the followingdescription and claim.

The drawing shows a gate with myimproved latch. It can be appliedequally well to a gate which opens either way, or to one which swingsonly in one direction.

Thelatch is intended to be made as shown, so as to be placed in theangle between the top and front bars h and i of the gate. The bracket 0is screwed to the under side of the top bar h, and the lug g, for thefulcrum of the bell-crank lever d, is secured to the inside of the frontbar '5. Then, by making a hole in the top bar for the rod 6, and one inthe front bar for the bolt a, the latch can be easily applied to thegate.

The end of the horizontal bolt a passes through and is supported by thebracket 0, while the center of the bolt is pivoted to the arm d ofthebell-crank lever d. The spring b is coiled around the bolt between theshoulder m and the bracket 0.

The bell-crank lever is constructed, preferably, with one short and onelong arm, the short arm, d, being pivoted to the bolt a, and the longarm, d, to the bottom of the vertical rod e.

The short arm, d, may be pivoted to a collar which slides on the bolt a,and which can be fastened at any point by a screw. The collar wouldserve as a shoulder for the spring b, and its position on the bolt acould be changed to suit the width of the front bar 2', to which thelatch is to be applied.

The rod 6 projects above the top of the gate and terminates in a knob,f.

By pressing upon the knob the bolt a is withdrawn and the gateunfastcned, and when the hand is raised from the knob the spring bforces forward the bolt into the position for latching the gate.

I claim as my invention- The combination of the bolt a, bell-crank lever01, vertical rod 6, with knob f, bracket 0, lug g, and spring b, thewhole arranged substantially as described, and for the purpose I JOHN D.CAMERON.
